London has been battered by 50mph winds that have felled trees and caused travel chaos. Powerful gusts swept across the capital as the Met Office issued a yellow "be aware" weather alert for most of the country.

The Australian radio station embroiled in the Royal baby hoax scandal has said it is reviewing its broadcasting practices and will help with investigations into the suspected suicide of nurse Jacintha Saldanha.

The owners of 2Day FM spoke out after British Police confirmed officers had contacted their Australian counterparts over the death.

Presenters Mel Greig and Michael Christian, who made the prank call that duped Ms Saldanha into helping reveal details about the Duchess of Cambridge's health, have also expressed a desire to speak about the tragedy.

Ms Saldanha, 46, apparently took her own life following the incident at the King Edward VII's Hospital.

Scotland Yard have contacted police in Sydney and it is understood they may wish to interview the two DJs, who present a show on the Australian station.

A spokeswoman for the station's parent company, Southern Cross Austereo, said the presenters want to speak out about Ms Saldanha's death. "They have expressed a desire to speak. We haven't ascertained when they're ready for that and how we're going to organise that, but they certainly want to," she said.

Ms Greig and Mr Christian have so far remained tight-lipped after the incident, and are receiving "intensive psychological counselling" to deal with the tragedy, The Australian newspaper said. The pair are on indefinite leave from the radio station, and have been bombarded with abusive and threatening messages on social media websites.

Meanwhile, Austereo's chairman, Max Moore-Wilton, replied to a letter from Lord Glenarthur, chairman of the King Edward VII's Hospital, in which he called for the "truly appalling" broadcast to "never be repeated".

In his reply, Mr Moore-Wilton described the events of the past few days as "tragic", but added: "As we have said in our own statements on the matter, the outcome was unforeseeable and very regrettable."

The letter goes on: "It is too early to know the full details leading to this tragic event and we are anxious to review the results of any investigation that may be made available to us or made public. We can assure you that we will be fully co-operative with all investigations."
